To Cynthia Trowbridge's request for data about Elysia viridis:
After the malacological workshop in the Azores (1991, I think), I brought some live Elysia viridis from there back to Copenhagen. With Dr. Bent Theisen I did electrophoretic studies on these specimens as well as specimens from a few Danish localities and from either Plymouth, England or Roscoff, France (specimens had been stored in the freezer). Our results showed a highly polymorphic species, and we could not separate populations from the 3 regions. Unfortunately the data have been lost; when Bent Theisen retired, he gave me a bunch of gels and prints, but the Elysia data were missing, and he has not been able to locate them among his things, so we have not been able to publish. However, I think that E. viridis is one highly plastic species. On the other hand, I have doubts about the identity of the E. viridis from South Africa, published by Gosliner, 1987. There are so many externally similar, but anatomically different species in the Indo-Pacific southern hemisphere.
